The paper developed a novel method of preparation of potassium ferrate by hypochlorite oxidation, and determined the optimal parameters. the experimental results demonstrate that fe ( vi ) compounds with high purity and yield can be prepared by raw technical materials. a variety of fe ( vi ) cathode materials, synthesized by potassium ferrate and alkaline - earth metal salts, provide a high - energy electrochemical discharge
採用改進的次氯酸鹽氧化法（濕法） ，以工業級的原料，在實驗室內，從1到4倍率規模合成高純度、高收率的fe （ ）化合物起始物? ?高鐵酸鉀，純度可達98 、收率在80以上；再以高鐵酸鉀為原料合成堿土金屬fe （ ）化合物或其他fe （ ）復合物，其中堿土金屬fe （ ）化合物純度可達94以上。 -
As for the method of preparing solid potassium ferrate from electrolytic synthesis of sodium ferrate solution, it is compared that the effects of the main procession facts of electrolysis upon both the anodic current efficiency and the relative concentration of na2feo4. one method was put forward to obtain high concentration of na2pe04 in the high concentration of alkaline by quick electrolyzing iron anode
針對由電解法合成na _ 2feo _ 4溶液進而制備固態k _ 2feo _ 4的方法，通過比較研究電解過程中主要工藝因素對陽極電流效率和相應na _ 2feo _ 4濃度的影響，提出了在濃堿液中快速電解鐵源陽極獲取高濃度na _ 2feo _ 4溶液的方法。 -
When using the method of periodically renewing electrolyte, the average current efficiency is 47. 3 % ( ii ) the solubility of k2feo4 in the solution of naoh is higher than that of the same concentration of koh solution and both of them become low with the growth of the alkaline concentration. the solubility of k2feo4 in the mixed solution of koh and naoh was influenced by both of common ions effect and salting - out effect and the influence of common ions effect is more heavy. the rate of methanol ' s reacting with k2feo4 is proportional to the content of water in the solid k2feo4. the stability of the potassium ferrate solution is far below the solid
（ 2 ） k _ 2feo _ 4在naoh溶液中的溶解度高於同濃度koh溶液中的溶解度，且溶解度均隨著堿溶液濃度的增大而降低； k _ 2feo _ 4在koh和naoh混合堿溶液中的溶解度，受到同離子效應和鹽效應的共同影響，且同離子效應的影響更大；固態k _ 2feo _ 4被甲醇還原的速度與甲醇或固態k _ 2feo _ 4的含水量成正比； k _ 2feo _ 4溶液的穩定性遠遠低於固態k _ 2feo _ 4 ，少量水的存在，可促使k _ 2feo _ 4按溶解?分解?再溶解?再分解的過程分解。
